Online advertising, a form of digital marketing, allows businesses to promote their products or services through various online platforms, including websites, search engines, and social media. It involves placing ads on these platforms, which are then displayed to targeted audiences based on specific criteria such as demographics, interests, and browsing history.
Online advertising has become increasingly important in recent years due to the widespread use of the internet and the growing popularity of online shopping. It provides businesses with a cost-effective and measurable way to reach a large and diverse audience, and it has become a major source of revenue for many online platforms.
